Patent EP-0055315-A1 (EP)
Inventor: HEDGES WALTER P
IPC: H02J3/00
Filed: 1980-12-30
Abstract: An energy management method and apparatus for use in conjunction with a demand-limit alternating current circuit having a plurality of separate loads, including resistive loads, and means for automatically shedding certain of the loads when the actual demand of the circuit exceeds the demand limited. The method and apparatus first establish a demand limit for the circuit. When the circuit is in use the actual demand of those loads in operation is sensed, there being a separate sensing of the demands imposed by certain of the operative resistive loads. There is then a reduction in the duty cycle of the power applied to certain ones of the operative resistive loads by switching the loads "off" and "on" synchronously with the zero points of the applied voltage, thereby to effect an overall reduction in the actual demand of the circuit when failure to make such a reduction would otherwise cause certain of the operating loads to be completely shed.

Abstract: Appareil de freins hydrauliques pour un vehicule ayant des freins (10) dont la mise en action se fait par ressort et le relachement par pression d'un fluide, les freins (10) etant mis en action par la defaillance ou perte de la pression hydraulique du vehicule. Les problemes techniques concernent le relachement des freins lorsqu'il n'y a plus de pression hydraulique dans le systeme ou lorsqu'elle baisse la purge des freins (10), et le controle du systeme de transmission. La solution comporte la structure d'une pompe manuelle (28) connectee au systeme de freins, une plaque terminale (14) ayant des orifices (16, 18, 20) ou se termine la canalisation de pression du fluide de systeme (22), la canalisation du frein (12) et la canalisation de pression de la pompe (76), et un tube en U (120) reliant les orifices (16, 18, 20) sur la plaque terminale (14). L'invention comprend aussi un clapet (140) d'isolation d'une conduite d'alimentation (134) tout en mettant a l'event une ligne ou canalisation de frein (133) pour verifier la pression du systeme. Un commutateur de limite (200) empeche le demarrage du moteur pendant que les freins (13) sont relaches manuellement.

Abstract: A method of metallizing a sintered ceramics material containing a silicon compound in which, on a surface of ceramics containing a silicon compound, a manganese-containing metal layer is formed and heated. To achieve a rapid reaction between the silicon compound and the manganese, the metal layer is formed so that it is substantially free from any gaps with the ceramics surface and the resultant structure is heated to a temperature lower than the melting point of manganese to effect the reaction. To form the metal layer, a deposited film is formed by vacuum- evaporation or sputtering manganese metal or a manganese alloy or a melt of a manganese-copper, manganese-nickel or manganese-titanium alloy is formed on the ceramics surface under the application of a pressure. This method can effect metallization at a low temperature and in a short period of time.
